DRAFT-RIGGING BACKS'ILOP.y

To @ZZ lw/liom 13 may concern: l Be it known that I, DONALD S. BARRoWs, a citizen of the United States, residing at Itochester, in the countyy of Monroe and State ofNew York, have invented'certain new and useful Improvements in Draft- Itigging Backstops; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to draft rigging backstops which are secured between the center sills or draft sills of a railway car to provide means for transmitting to the car underframing the bufling shocks to which the draft rigging is subjected in service. l

The principal object of the invention is to produce a backstop of great strength and simple form which is comparatively light in weight and may be readily attached to the car sills with small expenditure of labor.

The principal feature of the invention, generally stated, consists in forming a backstop with side walls adapted to be secured to the car sills and with a forward end wall which is united to said side walls and is adapted to form an abutment for a movable part of the draft rigging, and in bracing and supporting said end wall by means of a plurality of rearwardly divergent vertical webs disposed between the said side walls and integrally united at their forward ends to the said end wall.

A further feature of the invention consists in forming the backstop with side walls and with a forward end wall ,constituting an abutment for a movableV part of the draft rigging, and in supporting the said end wall against bufling shocks by means of a plurality o f rearwardly divergent webs which are spaced from said side walls and are united at their forward ends to said end wall, a plurality of parallel vertical webs being respectively united to the rear ends of said divergent webs and extending rearwardly therefrom. y

Another feature of the invention consists in farming a backstop with side walls and with a forward end wall united to saidside walls and adapted to afford an abutment for a movable part of the draft rigging, and in supporting the said end wall against butling shocks by means of a horizontal web extending between said side walls and united at its forward end to said end wall, the said backstop being also provided on opposite sides of the said horizontal web with a plurality of rearwardly divergent vertical webs'which are united at their forward ends to the said end wall and are also united to the horizontal web. t f

A still further feature of the invention resides in forming thel backstop withv side walls, an end wall adapted to constitute an abutment for a movable part of the draft rigging, a horizontal web united at its forward end to said end wall, and a centrally disposed vertical web united at its forward end to said end wall, and in also providing the backstop with rearwardly convergent vertical webs or flanges which are integrally united to said centrally disposed web and to said horizontal web. v

Other features Lof the invention residing in special details of construction and in the relations -of structural parts, will hereinafter.

appear. n y

In the drawings illustrating the invention, the scope whereof is pointed out in the claims, Y

` Figure 1 is a view,',partly in plan and partly in horizontalsectiom'of a portion of a railway car having a backstop involving the invention applied thereto, a well known type of draft rigging being shown as associated with the backstop.

Figure 2 is a View, partly in side elevationl and partly in vertical section, of the construction shown in Figure ,1. l

lVith the exception of the backstop, none of the features of constructioninventedby me and disclosed in the drawings is claimed in the present application. The draft rigging, which is of a well known type and which is chosen merely for the purpose of illustration, without intending to restrict the backstop to use in conjunction therewith, is

formed with a yoke l between the arms of which a pair of spaced follower blocks, 2 and 3 respectively, is mounted in a well known manner. Dot and dash diagonal lines fidiagrammatically representa yielding cushioning unit interposed between the said followers, while 5 'indicatesv the car coupler. The bufng shocks to which this special forni ofy draft rigging is subjected in service are communicated tothe backstop by the enfrageinent of the rear end of the draft yoke 1 with the forward end of said backstop.

The spaced center sills or draft sills 6 of the car underfraine niay be of any desired fo un.

The backstop is formed with longitudinally extending side walls 7 Vwhieh Vare respectively adapted to engage the inner faces of the adjacent sills 6, the said side walls preferably being` provided with three vcrtically spaced horizontally extending-gv rows of openings Vfor receiving rivets Swvhereby the structure may be securely vattached to the car sills. The outer ends of the side walls 7 preferably converge forwardlyv` as indicated at 9, and are united by a transversely extending end wall 10 'forming an abutmentfor a movable part of the dr Jft rigging, the said movable part in the presen-t instance being vthe draft yoke 1.

United to fthe end wall 10, preferably midway of yits height, is al horizontal web 11 which may advantageously extend rearwardly sufficiently far to be integrally connected to a -vertically disposed hollow colunin ladapted to receive a king bolt (not shown),tlie said horizontal web preferably being'the full width of the baclrstop between theside walls? thereof-and bein` integrally joined to the latter. ln the neighborhood of the king bolt column :12 the side walls 'T of the Ibaolstop are preferably also tied together by Ameans of transversely extending,` vertical flanges 13 which radiate frein and are integrally united to said column. The sidewalls 7 are also connected adj aeent the king bolt v column by a door plate or base plate 14 adapted to 'transmit the weight of the `car to a center bearing; (not shown); and a top plate 15 vintegrally uniting` the upper edges of the side walls 7 to the column 12 may also be employed if desired.

United at its forward end to the end wall 10 is a centrally disposed vertical web 16 which is integrally joined to the horizontal web 11 vand projects in opposite directions therefrom. The rear end of the web 16 is preferably directly united to the king bolt colunin V1 2, asshown, and may be extended vertieally at its rear end so as also to unite with the base plate 14 and the top plate The forward Yportion .of the centrally disposed web 16 ,is preferably of the sanie, or substantially t-hesame, height as the end wall l0.

The Yend wall 10 is braced and supported against bulling` shocks `by a plurality of rearwardly divergent vertical webs 17 disposed between the side walls 7 Von opposite sides ofthe horizontal web 11, the said divergent webs being united at their forward ends to the said end wall and being cast integral with the said horizontal web. As clearly shown in Figure f3, it preferred that the divergent Webs 17 vshall be formed, at points it said end wall7 1",.rcsultinzgin in r' in the n inhlfiorhood of The divergent braei tively united at their longitudinally fl' which extend rca verse web 1B with which connected. frein the side walls 7 and ",ni web 16 and preferably extend on sides of the horizontal web 1l for a less than the height of the said side v, At their points of junction with th`4 pa webs 197 the rearwardly divergent are united by rearwardly centen tic al webs or flanges 2O which are i connected te and project freni oppo of the horizontal web 11 and which pi ably entend from the centrally di, l c tical web 16 to the respective side walls 'T of the backstop.
